2g of K-Meta in 5 gallons is a dose of about 60ppm SO2 so a reading of 50ppm
is not out of the question but is likely higher than what you actually have.
I use Titretes as well and I keep my SO2 level at a minimum of 40ppm for
reds and 60ppm for whites. For wines with reasonable pH's, even if my
titrets are giving me the often quoted "20ppm too high" reading, I know I
will still be OK.

CHEERS!
